The OP seemed more interested in ranting about the state of drivers in Linux than in getting his device to work. He is sending the hardware and a couple of new disks to me so that I can figure what is wrong. He is currently trying to purchase a Panasonic drive on Ebay, as he claims that the coding is different than for the Matshitu drives. At least there is a different driver under DOS. These drives don't even have Windows drivers. I'm prepared to try his drive with FreeDOS on my machine when it arrives. Larry
